Elgin Anders Jr., O'Neal's neighbor, said he is responsible for the shooting.

"Big accident,” Anders said. “Huge accident."

He says he is friends with the O’Neal family and that he was grilling nearby and had slippery fingers when the gun accidentally went off.

"I should've just kept it in my pocket, but it was hanging in my pocket and I was like man I need to get it out my pocket,” Anders said. “I was about to put it where I put it at, and it slipped, and pow!"

Anders said he took O'Neal Jr. to the hospital instead of calling 911 for an ambulance because he was panicked.

"It was a shocking moment. It was a real shocking moment,” Anders said. “We didn't really know what to do so we took him ourselves. I'm holding him in my chest, squeezing the wound. So far, I’d seen the wound in his arm. Early this morning, they told me it came out his chest, but we didn't know nothing about it.”

Anders said as a father to a young child himself, he’s haunted by Saturday’s shooting.

"He's a young child,” Anders said. “Nobody wants to see anyone that young die.”

Christopher 2X said O’Neal’s father was in tears when he spoke to him Sunday morning.

"Nobody holds up well after any death but when it involves a child or a teenager, especially a child, the magnitude of that loss is indescribable to families,” 2X said.

Right now police say they are conducting a death investigation, with homicide detectives involved.
